Does not turn on


Hello

With any monitor, check the following to determine if the issue is MONITOR related or COMPUTER related.

1. Verify the monitor is receiving power - use a known good power outlet and plug it into the monitor

2. Samsung monitors have a light on the power button - are you getting any color light from this? Orange means it is in "stand by" mode and is waiting for the PC to send it a signal. Green means the monitor is getting a signal from the PC and the monitor is on.

3. With the monitor on, press the buttons on the monitor to bring up the OSD (on screen display) that changes the monitor settings. If you have a green light on the power button and press one of these buttons (AUTO works best), this will display the monitor adjustment options on the screen.

If you see the on screen adjustments, your monitor is working and the issue may be with your PC. Move the monitor to another PC and verify the monitor is working correctly.

IF you don't see anything on the screen and the power light is green, the monitor has failed.

This could be the lights that illuminate the screen have failed (something that happened to my Samsung Syncmaster monitors after about 6 years of use) or the screen has stopped functioning. In either case, replacement parts are hard to find and a monitor swap is likely.

Dell backlight indicators


A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

Green power light comes on goes off then on again stays solid, moniter says no signal, mouse lights up, and three red lights on key board flash then nothing why?


If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

My Dell Optiplex gx260 Pentium 4 Flat CPU doesn't Display anything, and Power light is Orange.. Please help me out


You say the power light is orange--I'm assuming that you mean the monitor.
This indicates the monitor is not receiving a signal from the computer.
Assuming that the computer actually powers up (fan runs, you can hear the hard drive being accessed, etc) then your problem lies in the video card.

If, on startup, you do see the BIOS info and maybe even the Windows splash screen before your monitor goes dark, then the problem lies in the video card drivers. In this case, starting in safe mode will work and allow you to download and install new drivers.

Hi, my monitor is "Samsung SyncMaster 793df". Problem is i can't set right color and contract. how can i solve it?


If the monitor has a consistent tint throughout, try to adjust the color through the OSD (On Screen Display). If this does not resolve the problem, or your monitor seems to be missing a color, disconnect the signal cable from your computer and wait for the No Signal image to appear. If all colors - red, green and blue - are present in the No Signal image, the problem is not with the monitor, but possibly with the video cable or video card. - exert from samsung faq....

If you mean something else, go into a little more detail if you wouldn't mind... Also, another thought has popped to my mind, you do have the drivers for your monitor installed?

I have a Samsung Syncmaster 740NW, using XP, I cannot change the screen resution using the "settings" tab in display properties to anything other than 800X600 pixels


Sounds a lot like your display driver is not installed properly. What is the make of the video card? It should display that information above the slider.

If it's blank or unknown on plug and play monitor (or whatever monitor you have), then the video driver is not installed properly. That's a whole other question which will require more information.

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

My acer laptop with windows xp will not allow me to select the optimal resolution for my samsung moniter. How do I fix this?


The Samsung SyncMaster 730b is a 17-inch analog and digital TFT-LCD monitor delivering crisp, clean text and bright, vivid colors. This display offers a 600:1 contrast ratio, 300 cd/m2 brightness, 1280 x 1024 resolution, 160/160 degree viewing angle, scanning frequency of 30-81 kHz horizontal and 56-75 Hz vertical and 0.294mm pixel pitch
The SyncMaster 730b display offers the option of using either a digital or analog interface for viewing images and text. The Digital Video Interface (DVI) ensures a shaper, cleaner image and a more accurate representation of the original video source. Since video starts out digital in a PC graphics card, the digital output is directly interfaced to the digital input of the LCD panel and always provides the optimum quality image. In addition, no adjustments are required with a digital display, even when randomly changing resolutions. Input connectors for this display include 15-pin D-sub and DVI-D. Available in black, the SyncMaster 730b delivers a maximum of 16.2 million colors. The monitor is Windows Plug and Play DDC 2B compatible
The important stuff here would be the following:
(1) 30-81 kHz horizontal and 56-75 Hz vertical
(2) SyncMaster 730b delivers a maximum of 16.2 million colors
(3) 1280 x 1024 resolution
nVidia card settings should not exceed these monitor parameters. The monitor is not designed for more performance output without increasing liability toward failure. ?. Put your card settings, under the nVidia tab, at the following:
(a) Refresh rate set at 75 Hz
(b) Set colors at 16 million
(c) Set resolution slightly less than 1280 x 1024
It?s quite possible your monitor is at fault, but start with its optimal parameter settings for the display card first. The display card probably exceeds the monitor?s capabilities. Hopefully, this will stabilize your PC session and the blank outs cease if hardware is not faulty
